' 1 Claim. (oi. -18) This invention appertains to incinerators of a type which is particularly adapted for use in private homes, but which is susceptible for use in large apartments and other buildings.

One of the primary objects of my invention is to provide novel means for feeding the air for combustion downwardly and directly on the surface of the burning waste, instead of relying on the air fed from below the grates, which heretofore was the accepted method, thereby bringing about the proper and complete combustion of the waste.

Another important object of my invention is to provide an incinerator in which the air for combustion is fed around a gas burner and directed downwardly against the surface of the waste, so that an adequate supply of air will be furnished at the proper point for supporting combustion both of gas and waste, whereby an intense fire is insured on the grate for properly consuming all of the waste.

A further object of my invention is the provision of an incinerator having its main air inlet for combustion and drying admitted above the grates and so arranged that the air entering the combustion chamber is directed downwardly at an angle between the vertical and horizontal for impinging on the surface of the burning waste, the inlet being arranged around the gas burner, so that the flow of gas will tend to draw the air into the combustion chamber in connection with the draft formed by the flue.

A further object of my invention is to provide an incinerator including a gas burner having its nozzle in the center of an air orifice so that the travel of the gas is parallel to the column of air passing through the orifice whereby the flame is elongated and carried downwardly onto the surface of the material to be consumed.

A further object of my invent1on is the provision of novel means for placing the burner immediately above the firing door, so that the burner will be readily accessible for lighting through the door opening without the need of a pilot light.

A further object of my invention is the provision of an incinerator having the air orifice and gas burner arranged immediately above the firing door and within the thickness of the wall so that the same will be .out of the path of material falling into the combustion chamber and thoroughly protected therefrom, whereby the orifice and nozzle will be prevented from becoming foul by said material.

A still further object of my invention is to provide an improved incinerator of the above character, whichwill be durable and efiicient in use, one that will be simple and easy to manufacture and one which can be incorporated. with a building :at'a comparatively lowcost.

With these and other objects in view, the invention consists in the novel construction, arrangementand formation of parts, as will be hereinafter more specifically described, claimed and illustrating in the accompanying drawing, in

which:

The figure is a vertical section through an incinerator constructed in accordance with my invention.

Referring to the drawing in detail, the letter A generally indicates my improved incinerator, which comprises the front and rear walls 5 and 6, and the side walls 1. The incinerator may be built as part of one of the retaining walls of the building and is preferably disposed in the cellar or basement of the building. Communicating with the upper end of the incinerator is the flue or chimney 8, which can be provided at the proper point, if so desired, with intake openings for permitting the placing of waste into the chimney for disposition upon the horizontal grate 9 arranged in the combustion chamber of the incinerator. The space below the grate 9 forms an ash pit l0 and a door H can be provided for facilitating the removal of ashes from the pit. The grate 9 can be of any character, but I prefer to construct the same of the dumping type.

Referring again tothe chimney or flue 8, it is to be noted that the front wall 5 of the incinerator is offset from said flue or chimney and is located slightly in advance of the same defining a shoulder l2 between the front wall and chimney or flue.

The front Wall 5 above the grate 9 can be provided with a fire door [5 which can be utilized also for the placing of the waste to be burned into the combustion chamber onto the grate.

Directly above the fire door l5 and within the plane of the inner and outer faces of the front wall 5 I arrange an air chamber 5, which can be formed of cast iron or any other desired material. The chamber l6 has its front end preferably left open as at I! and a baffle plate I8 is placed in front of the open end of the chamber in slightly spaced relation thereto, to define air entrance openings around the baflle plate for the chamber.

The bottom wall I9 of the air chamber l6 has its rear end offset and set at an angle to the horizontal as at 20 and the inclined portion 20 of the bottom wall is provided with an air orifice 2|.

Extending through the baffle plate I8 is a gas within certain limits and the angle of this wall determines the angle of the path of the flame 7 burner 22. This burner 22 is provided with a curved nozzle 23 which extends downwardly at an angle through the axial center of the air discharge orifice 2|. This nozzle 23 is directed toward the grate 9 and is arranged at an angle to the horizontal and vertical as is clearly shown in the drawing. The usual air mixer 24 can be provided for the burner and a control cook 25 is utilized for governing the control of gas to the burner. Any suitable source of supply of gas .for the burner can be utilized.

By having the nozzle of the burner directed downwardly at an angle and arranged in the axial center of the air discharge orifice, the travel of the gas is parallel to the column of air passing through the orifice. This elongates the flame and the flame is carried downwardly onto the surface of the material on the grate, thereby insuring the proper consuming of the waste. By taking the air above the top of the grate,.the air can be directed downwardly so as to impinge on the surface of the waste which will tend to dry the waste and properly support the combustion thereof.

As heretofore stated, the burner nozzle and air discharge orifice are located within the plane of the rear face of the front wall and thus, the orifice and the nozzle are completely protected from the waste falling onto the grate. This prevents the fouling of the burner nozzle and the orifice. It is to be also noted that the shoulder l2 of the incinerator nozzle acts as a guard for the orifice and the nozzle;

The angle of the inclined portion 20 of the bottom wall of the air chamber can be varied and air on the waste. The outlet end of the nozzle is preferably maintained at all times substantially at right angles to the face of the inclined portion 20 of the bottom wall of the air chamber.

From the foregoing description, it can be seen that I have provided an exceptionally simple form of incinerator in which the proper consumption of waste is insured.

Changes in details may be made without departing from the spirit or the scope of this invention, but what I claim as new is:

In an incinerator, an incinerator body, a grate in said body for reception of refuse, a chute for directing refuse onto the grate, one of the walls of the body being offset with relation to the chute and located in advance thereof, an air inlet box arranged a material distance above the grate and within said wall having an air inlet at its'front grate, the travel of the gas from the nozzle being parallel to the column of air passing through the orifice whereby the flame from the burner will be elongated and carried downwardly toward the surface of the refuse.
